SummaryLive, from New York, it’s Saturday Night Live 25!Yes, at season’s end it will have been twenty-five wild and unusual years since “SNL” debuted across America. And most of the current cast celebrates five years with the intent to finalize their contracts with “Saturday Night Live”. Indeed, by the second half of the season, newcomers Jimmy Fallon, Chris Parnell, Horatio Sanz and Rachel Dratch start appearing in more sketches than Will Ferrell, Cheri Oteri or Tim Meadows formerly have. Even four-year veteran Tracy Morgan begins to build more ground this season (and about time!).Many new characters are introduced this season. Some, like the Boston Teenagers (Jimmy Fallon and Rachel Dratch) and obnoxious Company Computer Guy Nick Burns (Fallon), are welcomed by viewers; while characters like 50-year-old Sally O’Malley (Molly Shannon) manage to get shunned before the sketch has ended.Overall, 1999 is one of the more unstable seasons in “Saturday Night Live”‘s history. Viewers either like the cast or they don’t – but when Chris Kattan’s recurring character Mango makes more appearances than even producer Lorne Michaels, it’s time once again to restructure the format of the show.
